Question
How do I find the heat gained by water?
Transcribed Image Text:**Transcription for Educational Use**
The table contains data from two trials regarding a calorimetry experiment. Below is a detailed breakdown of the columns and their respective values:
| Trial | Mass of metal sample (g) | Temperature of water (boiling) (°C) | Mass of calorimeter (g) | Mass of water (g) | Temperature of the water in calorimeter (°C) | Temperature of water (final) (°C) | Temperature change of water, ΔT (°C) | Heat gained by water (J) | Temperature change of metal, ΔT (°C) | Specific heat of metal (J/g°C) |
|-------|----------------------------|----------------------------------|------------------------|------------------|--------------------------------------------|-------------------------------|----------------------------------|--------------------------|---------------------------------|------------------------|
| 1 | 35.296 | 94.2 | 36.369 | 118.346 | 21.458 | 29.491 | 8.4091 | 4.24 | 65.9 | 2.43 |
| 2 | 32.231 | 90.7 | 30.278 | 120.453 | 22.5 | 24.9 | 2.4 | 1.4 | 69.6 | 2.5 |
**Average specific heat of the metal (J/g°C):** Calculated from the trials' specific heats.
**Theoretical Specific Heat:** Provided for comparison but not listed in this table.
**Theoretical Metal:** The expected metal type based on the theoretical specific heat value.
**Percent Error:** Not calculated in this table, but necessary for understanding the accuracy of the experiment.
This data is useful for understanding calorimetry, the specific heat capacity calculations, and experimental error analysis. Each trial offers insight into how different variables affect the heat exchange in a calorimetry experiment.
